Three LED-indicators for immediate status reporting THE TRANSPARENT KEY TO SECURE WIRELESS NETWORKING 11 MBPS WIRELESS LAN ACCESS POINT Wireless networking 11 MBPS WIRELESS LAN ACCESS POINT www.nowiresneeded.com The 11 Mbps WLAN Access Point is an indispensable building block of your wireless infrastructure. This compact, reliable device is easy to install and can be centrally managed from any place in your network. Each 11 Mbps WLAN Access Point offers a number of channels to create a non-interfering, multiple pico cell structure, enabling you to build a complete wireless premises network. The high-speed data rate of 11 Mbps makes it possible to run virtually any application you prefer wirelessly. The Access Point is capable of supporting several virtual LANs over a single wireless enterprise network. With the included management utility called APCenter, you can drag and drop installed Access Points and update the new Access Point with all the current characteristics. Wireless networking NoWires Needed has developed a range of high-speed, high security wireless LAN products that are embraced by organizations all over the world for the many advan- tages they provide. These advantages include higher efficiency and lower total costs of ownership (TCO). High-speed wireless networks enable hot-desking and other forms of flexible offices. New or temporary workplaces are created in a matter of minutes, rather than days. Exhibition sites, conference centers, airports and hotels can offer instant Internet access to their visitors. Security has been taken care of, using AirLock™ advanced security architecture Eavesdropping and data hacking are major issues in the networking business. The risks are perceived to be even higher when operating a wireless network. NoWires Needed has developed a superior solution to this problem and dubbed it AirLock™. AirLock™ prevents eavesdropping by using an access control list and an advanced public/private key algorithm, whilst data hacking has been taken care of by a dyna- mic 128-bit encryption key. AirLock™ also relieves your network administrator from the burden of additional key management. The strongest link is always used, ASBF™ takes care of it Automatic Scale Back Functionality scales back to lower data rates if necessary when communicating with other IEEE 802.11 compliant equipment. It also ensures that the users get the best connection available in radio-hostile environments. Plug-and-Play It goes without saying that the products of NoWires Needed have plug-and-play capabilities. The 11 Mbps WLAN Access Point can be deployed in any Ethernet- based network. Many network operating systems are supported, including NT, Novell, AS/400 and Linux. Note that APCenter Management Software should be run on a PC under Windows (95, 98, NT4.x, 2000). NoWiresNeeded NoWires Needed is strongly committed to offer its customers high-speed, high secu- rity wireless access solutions by deploying state-of-the-art technology. This commit- ment has resulted in the release of our latest range of wireless networking products, offering breakthrough speeds of up to 11 Mbps. Specifications Standards compliance:

Page 1 of 3 Processing Gain - Theoretical calculations The processing gain is related to the jamming margin as follows [2]: system output p L S J N S GΗ       Η       Ζ Where BER REFERENCE is the reference bit error ratio with its corresponding, theoretical output signal to noise ratio per symbol, (S/N) output , (J/S) is the jamming margin (jamming signal power relative to desired signal power), and L system are the system implementation losses. The maximum allowed total system implementation loss is 2 dB. The HFA3861A direct sequence spread spectrum baseband processor uses CCK modulation which is a form of M-ary Orthogonal Keying. The BER performance curve is given by [5]: “ The probability of error for generalized M-ary Orthogonal signaling using coherent demodulation is given by: PPQz E z dz ec b M S N ΖθΖθθΗ         θ      θ θ  11 1 2 212 2 1 2 1 2 01 0 ↓ ♣ ()exp This integral cannot be solved in closed form, and numerical integration must be used. There are error rate extensions for differential decoding and descrambling that are also to be accounted for. This is done in a MATHCAD environment and is displayed in graphical format below. Page 2 of 3 1.11000 byte PER vs. Es/No 15.51616.517 10 -2 10 -1 10 0 11 Mbps CCK in Thermal Noise Es/No (dB) 1000 byte Packet Error Rate The reference PER is specified as 8% . The corresponding Es/No (signal to noise ratio per symbol) is 16.4 dB. The Es/No required to achieve the desired BER with maximum system implementation losses is 18.4 dB. The minimum processing gain is again, 10 dB, therefore: dB S J dBdBL S J N E G system output o s p 100.24.16∫       ΗΗΖΗ       Η         Ζ dB S J dBG p 104.18∫       ΗΖ The minimum jammer to signal ratio is as follows: dB S J 4.8θ∫       For the case of the HFA3861A, the bit rates are 1, 2, 5.5, and 11 Mbps. The corresponding symbol rates are 1, 1, 1.375, and 1.375 MSps. The chip rate is always 11 MCps, so the ratio of chip rate to symbol rate is 11:1 for the 1 and 2 Mbps rates and 8:1 for the 5.5 and 11 Mbps rates. Since the symbol rate to bit rate is less than 10 for the higher rates, we supply the theoretical processing gain calculation for these cases where spread spectrum processing gain with embedded coding gain is utilized. This is reasonable in that they cannot be separated in the demodulation process. If a separable FEC coding scheme were used, we would not be comfortable making this assertion. Page 3 of 3 As can be seen from the curve of figure 1, the Es/N0 is 16.4 dB at the PER of 8%. This PER can be related to a BER of 1e-5 on 1000 byte packets. With 8 bits per symbol, the Eb/N0 is then 7.4 dB or 9 dB less than the Es/N0. It is well known that the Eb/N0 of BPSK is 9.6 dB for 1e-5 BER, so therefore the coding gain of CCK over BPSK is 2.2 dB. We add this to the processing gain of 9 dB to get 11.2 dB overall processing gain for the CW jammer test. Taking the calculations above, if the dB S J 4.8θ∫       then the equipment passes the CW jamming test.
